(cine-4) l wFigurefi is-a view, simllarfto Figure 2, illus'-- This invention relates to loose leafbinders and particularly to a binder for the reception of pages :or leaves-from time to timeuntil the binder is filled and-the pages or leaves are'ther eafter use as a permanent record.

. The invention has todo particularly with a leaf" impalingjstructure which is particularly eco nomical and simple in operation, .andwhichprovides ments etc., by making "photostaticiflcopies there- 1 of, and-the binder herein referred to is'particularly suitable for this recording process. The photostat paper is 'purchased'in'rolls, similar to a camera film, and after thisupaper has been exposed, the exposedqportions are cut from the roll or film and are developeckand are subse- .quently cut to size and perforated along one edge to receive the impaling posts of the binder. .It is difiicult to cut'each and every portion of the photostat paper, which constitutesa page or leaf of the binder, to exactly the same dimensions and to exactly locate the post perforations in each sheet, withthe result that the .bookappears'unattractive. The appearance of the 'binder is greatly improved by trimming the uneven edges .of theleaves. 7 i

Accordingly, one iOf the important objects of this invention is aibinder embodying a structure which permits the leaf impaling unit and the leaves I secured thereinto be removed. as a bound "section of the binder, .andwhereby all of the leaves secured in the leaf impaling unit may be simultaneously trimmed to size. a The invention consists -in the novel features and in the combinations and constructions hereinafterset/forth and claimed.

-In describing this invention, reference is had to the accompanying :drawings in which like characters designate corresponding parts in all the views. v

' Figure 1 is anisometric View of a binder em- -.bodying our invention illustrating the arrangeview of the I trating the relative-arrangement of the parts with the upper ends of the posts detached from the backmember and positioned to receive additional pages.

. 4 Figure '16 is an end elevational view ofthe leaf 'impalingunit'filledwith leaves and removed from thetbinder to permit trimming of the pages.

The invention consists generally of a back @member, covers hinged along each edge of the "back member, a" leaf impaling Lunit' including I a' f pl-uralityzo'f osts secured together in spaced apart relationship and arranged transverselyof the back member, means for detachably and pivotallyse- .zcuring- :one sidegofrthe leaf-.impaling'uni-t to one edge of .the back member,-'and means cooperable "withajs aidposts and-the back member for detachablysecuring the free ends of the posts to the back .member-andbteing operable to clamp. the leaves 01. pagesqonithe posts.

.The.;b ack member here shown consists of plates Ni l-l1 ,v Theplateflll is of channel :forma- .tion ,in cross --section ;having rearwardly extend in-g -side flanges l2 which terminate in eyes l3 and :an outer plate or. covering '1 I whichis riveted or otherwise secured to the-flanges (2 of the back member.

The :inner' plate ll is formed along one edge with an'inwardly extending "flange It also provided with eyes "20 spaced apart to receive the lower ends of the leaf impaling posts 2|. The

"plates :I 0, H are riveted, spot welded, or other; wise secured" together. The inner plate II is *providedwith two or more slots 22 extending up wardlyfrom a point adjacent the lower end or flange IS. The rearplate llfl is formed withslots "-23 extending transversely of the plate and "through the base ofthe flanges l2. Theslots23 are arranged ingregister with the slots 22 but are preferably of greater width asillustrated in Figures 1 and 4. i H v I The removable leaf impaling unit includes a plurality of posts 2|; formed withflnotches 25 on opposite side edges, and preferably. a centrally arranged post 26 having plain side faces. The postsZI ZB are rigidly secured to ,a bottom plate of the posts, ;and the posts areisecured to the 121. In thepstructure-shown, thebottom plate '21 .is formed with apertures to receive the lower ends plate 21 by welding, brazing, or swedging, as shown in Figure 2.

The leaf impaling unit is preferably pivotally secured to the adjacent edge of the back member,

and as here shown the lower ends'of the posts 2!, 25 extend through the plate 21 and are p-rovided with apertures to receive v a hinge rod.,,29 arranged in 'the'eyes 251 I It,

The leaf i paling unit further includes a top .platefid formed with notches 3! extending in: wardly from one edge to receive the posts 21, 2'61 The opposite edge of the plate is formedpor provided with rearwardly extending projections 33 of such width and so arranged; as-to'be slid able in the slots 22 of the plate H, The proje tions 33 are also formed with ears 32 extending in a lengthwise direction of the plate 3|] and engaging the rear marginal surface of the plate l'-l The ears .32 are I along the sides of the slots 22. I slidable in the wider slots 23 formed in the rear I plate I El, and the plate 30 may be readily removed from engagementwith the back member-by 'moving the same upwardly, the slots 23 in the flanges l2.permittlng the projections 33 to move outlet engagement with the plates H], H.

'- In order to maintainthe free ends of the posts.

2 l, 25' in the slots 3!,a suitable latch 34 is mounted on the plate 30 and is arrangedto 'be shiftable in position toengage the post 25, as clearly illustrated in Figures 1 and 3; It will be observed "1 that the free ends'of the posts are detachably :are maintained in parallel leaves or pages on the posts 2|, 25.

such as steel or bronze; and which may be se-, cured 'tothe plate 30 as by rivets or-any suitable The post engaging members fastening means. 35 are arranged in register with the slots 3| and a are provided with slots to receive the posts 2|.

The members 36 are provided or formed with inwardly and upwardly extending flexible flanges 38 arranged to engage the notches 25 in the side edges of the posts 2|;

It will be apparent that as the plate 3Uis moved downwardly over the posts 2!, the flanges "38 will ratchet .over the serrations 25until downward movement of the plate ceases upon engagement with the leaves on the posts. With this structure,

the leaves are tightly and neatly clamped be; tween the bottom plate Z'land the plate 39. It is to be understood that theleaves, .prior to insertion receive the posts 2|, 26.

the binder, are provided with perforations to vWhenit is desired to add additional pages, it"

is only necessary to move the latch a l out of engagement with post 26 and the back member then may be swung rearwardly away from the posts and leaves, as indicated in Figure 5. .The additional leaves may be then conveniently in seited over. theposts, and the back member swung inwardly until-the free ends of the postsare positioned in the notches 3|. The latch 34 is then shifted into post engaging position, as shown in Figure l, and the plate 3!! pressed downwardly.

After the binder is filled and it is desired to trim theedges of the leaves, the hinge rod 29 is withdrawn releasing the lower ends of the posts .fber, a removable leaf impalingunit including a ,bottom plate and a plurality of ,postsrigidly,

of said notches and havingyielding flanges coopber, covers hinged to each edge ofthe back m'em- I her, a removable leaf impaling unit including a from the back member, and the entire'u'nit may be then raised upwardly until'theflprojections 33] pass out of the slots 22, 23. Figure 6 illustrates the leaf impaling unit and leaves removed from the binder.. In this condition the leaves can be ,-6

conveniently. and accurately trimmed and the unit is reinserted in the binder by sliding the projec- I tions 33 downwardly in theslots, 22 23,-and in- 1 serting the rod 29 to secure the lowerends of the posts to the back member.

What we claim is:
